In a glass box, there's very little volume compared to ponds, lakes or rivers, so a large difference in temperature may cause shock to the fish. To be safe, try to make sure the difference is
not more than 2 or maybe 3 degrees F
.
Can temperature fluctuations kill fish?
Even though their bodies are the same temperature as the water,
extreme changes can kill them
— changes such as a sudden drop or rise in the water temperature, stemming from a cold front moving in, or southern air sweeping across New England.
How much of a temperature change will shock fish?
I manage to keep mine to
1-2 °C
temperature change when doing up to 50% water changes. That is, the new water is warmer than the existing, and I add cold until it's at least within 1-2 °C, normally and then siphon it into the tank. I can get it down to 0.5 °C without too much difficulty.
What will happen to the fish if the temperature drops?
Fish use different enzymes to regulate their bodies for different temperatures. So, if the water gets colder or warmer, they readjust which enzymes they use. The more drastic the temperature change, the more time they need to adjust. This explains why
the marsh became a ghost town
when the water temperature plummeted.
Is 82 degrees too hot for tropical fish?

80°F
for a short period of time, though it may cause complications to develop. At higher temperatures, aquarium fish require more food because their metabolisms have to work that much harder.
How long does it take for fish to adjust to water temperature?
Most people will tell you that it takes about
15 minutes
for fish to acclimate to an aquarium. While this is partially true, it takes at least an hour for a new fish to adjust entirely to a new environment. Float the bag in the aquarium until the water reaches the same temperature as that in the aquarium.
